Letters Patent NQ. 95,844, dated October` 12, 1869.

HOUSE- CCNNECTION FOR SEWER, WATER, AND GAS-PIPES.

The Schedule referred to in these Letters Patent and making part of the lame.

Figure 1 represents a transverse section ofja street, showing my invention.

Figure 2 is a similar section of a modification there-A of Y Similar letters indicate -corresponding parts.

This invention consists in the arrangement of tubes leading from a tunnel situated under the street, and enclosingthe main sewer, water, and gas-pipes, into the houses on the opposite sides of the street, said tubes serving to enclose the house-connections of the sewer, water, and gas-pipes in such a manner,l that if said connections, or either oi them, are getting out of order orvdefective, they can readily be removed and" replaced, without the necessity of tearing up the pavement and digging down to said connections, a necessity Which is unavoidable with the housc-connections of sewer, water, and gas-pipes as now arranged, and which causes much inconvenience and expense."

In the drawingsv The letter A designates a tunnel, of sufficient interior size to admit the sewer, water, and gas-pipes, and to allow suiicient room for the passage of the workmen wit-hin it.

lIl his tunnel may be constructed of brick, or of such other material as may be convenient, and its shape may vbe-such as shown in Gg. 1 of the drawing, or it may be builtin the shape shown in lig..2, with a depression, BP, to serve as the main sewer, or it may be builtin any other convenient shape or man'ner.

Through this tunnel extend the sewer-pipe B, the water-pipe C, and the gas-pipeD, said pipes being arranged and secured therein in any convenient manner.

From these pipes extend the connections b c ll to the houses on the opposite sides of the street, and these connections are enclosed in tubes E, which pass from the sidesof the tunnel to and through the walls o f the houses, `being open at both ends, so that either of said house-connections can be readily taken out and replaced, without tearing open the pavement in the street and digging down to it.

In order to prevent the house-connections from getting mixed up or from intelfering one with'the other,

.they may be kept separate in the tubes E, by suitable braces or partitions.

After the several house-connectionshave been properly made, the inner ends of the tubes E may be closed bysuitable lutng, which can be readily relnoved, if

the necessity arises, and which, when not removed, will prevent any nauscous gases or odors passing from the tunnel A into the houses.

It is needless to enlarge on the advantages of Amy tubes for enclosing the house-connections b c (1 -they are self-evident.

With the present arrangement of said connections,- itis unavoidable, if either of them gets -out of order and requires repairs, that the pavement. iu the street shall be tom up, and a hole dug, 'until the defective connection is reached, an operation which not only necessitates much expense and delay, but which, in

most cases, 'tends to disfigure or actually injure the pavement, according to the nature or construction ot" the same.

By enclosing the house-connections in'the tubes E.. I' am lenabled to remove either or all of them, and to replace them with the leastpossible trouble or delay, the pavement does not require to be disturbed, and

said connections can be kept in order with the greatest ease and facility.

It is obvious that the tunnels A may also be made to enclose a pipe fbr"teleg1aphwires', or other purposes, and in this case corresponding connections will be made to pass through the tubes E;

If desired, my tubes E may also be applied to enclose the connection of a lamp-post with a gas-main, or the connection of a hydrant with a water-main, and in either case, the advantages of said tubes are readily understood from the foregoing description.

I do not claim a tunnel running along under the vcentre ofa street, and containing gas, water, and sewer-pipes. Neither do I claim to provide -each tunnel with openings in its sides, to admit the. house-connections of the gas, water, and sewer-pipes; but

What I claim as new, and desire to secure Aby Letters Patent, is

The tubular cases E, extending from the houses on the opposite sides of a street, under said street, and into the sides of' the tunnel A, to'forin permanent channels, through which the house-connectionsof gas, water, and sewer-pipes, either or all, can be introduced, without disturbing the street or sidewalk, as shown and described.
